Odd thing in lua-library

[George Sedov <radist morse gmail com>]

Hi guys,

Since Toso said that I should use the maillist when I want a quick
reaction, I'm writing here.

Please, look at this line:

https://git.gnome.org/browse/grilo-plugins/tree/src/lua-factory/grl-lua
-library.c#n809

Is there supposed to be "3"? I don't see "2" used anywhere, but maybe
I'm missing something.

Cheers,
        George
